Hi all

I'm having a wonder about this and hoping for some help.

I have a Fujitsu Scansnap, and I have chopped three hundred novels (no images), and scanned into Scansnap scanner at Best Mode (Color & Grayscale 300 dpi, Monochrome 600 dpi).

Normal Mode - Color & Grayscale 150 dpi, Monochrome 300 dpi
Better Mode - Color & Grayscale 200 dpi, Monochrome 400 dpi
Best Mode - Color & Grayscale 300 dpi, Monochrome 600 dpi
Excellent Mode - Color & Grayscale 600 dpi, Monochrome 1200 dpi


My Scansnap also scans at excellent mode, but this is very slow, and the file size is huge.

The 300dpi seems fine both on my 6 inch Kindle 2nd gen, and on my iPad Air. I wish to read the pdfs rather than convert into mobi ising OCR etc

I have a few questions for expert MR readers:

If I am reading pdf standard novels (no pics):
1) Is Best Mode - Color & Grayscale 300 dpi, Monochrome 600 dpi sufficient?
2) If I want to future-proof the pdf-scanned-books, do I need to scan at excellent mode too. Do you antipate it is useful to instead capture them at excellent mode because of future e-readers and tablets that are yet to be released?

Any help is appreciated because I am running out of space and wish to recycle the 300 detroyed books, and don't really wish to scan them all a second time but more slowly just to get them in 600dpi unless absolutely neccessary.

Many thanks for any advice which can be offered.
